Rania, who is married to Jordan's King Abdullah II of Jordan, is known for her elegant style and frequently pushes the boundaries with her fashion choices.

Although she has multiple piercings in her ears, Rania has worn them all at once only at a handful of times during her public events.

Last week at a function with Germany's chancellor Angela Merkel, Rania was pictured wearing a large hoop of glittering diamonds with a small stud above the earring. And up the top of her ear, Rania wore another diamond stud – taking the total to three.

And in 2017 at the Jordanian opening of parliament, Queen Rania went all out - wearing four pairs of earrings. At the top of her ear she had two small hoops, while below she wore an ear climber and another hoop.

Rania chose several white gold earrings during a visit to New York in 2015, for a United Nations gender equality event.

In a 2006 interview with ElleRania addressed why, as a Muslim woman, she chooses not to wear a hijab.

"You’re not forced to wear a veil and that is a personal decision on my part not to wear the veil," Rania told the publication.

"For me, whether you wear the veil or not, is not an expression on your views of women; it doesn’t reflect on the status of women.

"I think, as with every other woman, your clothes are an expression of yourself and of how you feel, and I have found that, over the years, I’ve gotten comfortable with a particular style.

"When I choose something to wear, I realise that I’m not just dressing for myself, especially when I am abroad, I’m representing my country, I’m representing my people, so I have to always make sure that, I’m representing them the best way I possibly can."
